This solution reduces the damage caused to people on the ground when the decorative board falls off the wall.

Description

technical field [0001] The invention relates to the field of wall decoration, in particular to a prefabricated building wall sound insulation composite decorative board. Background technique [0002] With the continuous deepening of China's urbanization process, the new army of the construction industry - new prefabricated buildings (such as prefabricated commercial houses, container houses, prefab houses, prefabricated houses, wooden houses, villas and resort houses, etc.) will become my country's next 30 In the transformation direction of the real estate industry, the original reinforced concrete buildings will be replaced by prefabricated buildings by at least 30%, so the demand for decorative wall panels in the construction market is also huge. [0003] Since the decorative board is installed on the wall, the connection between the decorative board and the wall will become weak due to aging and corrosion after a long time, so when encountering natural disasters such as st...
